I ordered a new BMW X3 20i in February. The dealer sent me the spec of the car on and the documentation showed the colour I wanted. I confirmed the spec by reply email and asked him to order the car. Later he sent me a 'Sales Invoice' to scan and sign, but he had made a clerical error and put the wrong colour on the document. I scanned and signed the document and sent it back without realising the dealer had input the wrong colour on it.

In June - last week - I went to the dealership to pick up the car. I immediately noticed that it was the wrong colour and said so. They said to sign the paperwork and that it could be re-sprayed. I left the dealership in the car. I sent the manager of the dealership the paper trail of emails and documents, complaining that the car I was in possession of was the wrong colour and this should be corrected, and I could not accept this new car in the colour.

The BMW manager has never acknowledged or accepted that it is their employee's fault in ordering a car in the wrong colour. I have logged a complaint to Customer Services BMW. I wish to return the car - five days after pick up - with 71 miles on it.

The manager is now saying that I should either:

1. Return the car to them and wait for a new car in the correct colour and pay a further £9000 for delivery early October.
2. Sell the vehicle outright (value now £36,000 on a car that cost me £50,000)
3. Re-paint the car completely at a cost of £11,500
4. Effect a 'painted wrap' on the car at a cost of £7000

All at my cost. They have not accepted their fault in this. I don't see why I should pay for this error. What is the legal position on this? Should I instruct solicitors?
